What do you have for a pressure gauge? You just need to tap into the line to the regulator and see how much pressure you have with the engine running.

i put a gauge on the side of the regulator i took a plug out

I took the plug out of the regulator on the side and put a gauge there. It showed 5 lb. The same as the other two gauges I already have on the car
